Answer:
64/729
or 0.088 to 3 decimal places.
Step-by-step explanation:
The probability of no 2 and no 3 on one throw of the dices = 4/6 = 2/3.
For 6 rolls we multiply this 6 times because each throw is independent.
The answer is (2/3)^6
= 64/729
or 0.088 to 3 decimal places.

Explanation:
A)
Let t and f represent the numbers of two-point and four-point questions, respectively.
__
B) The number of points for each type of question is the product of the point-value per question and the number of questions of that type.
2t + 4f = 100 . . . . . the test is worth 100 points
t + f = 40 . . . . . . . . there are 40 questions on the test
_____
<em>Additional comment</em>
The test will have 30 two-point questions and 10 four-point questions.
